What type of filter?

Hi 2 all,
I need to know what type of filter is the circuit below and under what conditions of input frequencies and output signals it will work as a filter?

if the circuit image is not below then plz check the attachment

 

Re: What type of filter?

Let us analyze it
current form i/p to the inverting node = current from it to the o/p
Vi/(Ri + 1/jωCi) = - Vo /Rf
Vo/Vi=-Rf Ci s /(1+ Ri Ci s)
s =jω
So we have a zero at zero frequncy and a pole at ω = 1/Ri Ci.
So this is a high pass filter whose corner frquency is f = 1/(2π Ri Ci)
